The present invention relates to the field of computer technologies, and in particular, to a method, an apparatus, a device, and a medium for establishing a wake-up instruction database.
Background
China is wide in territory and various in languages, such as Guangdong language, Hakka language, Minnan language, Chaoshan language and the like, although the Guangdong language and the Mandarin language are unified into the Mandarin language at last, dialect accents in various regions are always mixed, and even northeast and Sichuan of the Mandarin language have strong regional accent differences.
However, the current voice wake-up recognition is mostly a standard wake-up password, either mandarin, cantonese or other dialects, but a cantonese speaker has difficulty in completing accurate command transmission or wake-up by mandarin, so that the voice wake-up cannot be only a standard voice wake-up command, and the voice wake-up command can be continuously adapted to your dialect mandarin according to your language characteristics.
That is, the existing voice wake-up algorithm is only suitable for mandarin pronunciation, and when the pronunciation is not standard, the accuracy of voice wake-up will be reduced sharply, so it is very necessary to establish a region-based wake-up command database.

And 102, adding awakening voice data to a voice database corresponding to a pre-established geographic area to which a geographic position belongs based on the pre-divided geographic area to obtain an awakening instruction database corresponding to the geographic area.
In specific implementation, different geographical areas are divided in advance, after the geographical position reported by the terminal equipment and the awakening voice data are obtained, the awakening voice data are added into a voice database corresponding to the geographical area to which the geographical position belongs, which is established in advance, according to the divided different geographical areas.
In a possible implementation manner, adding wake-up voice data to a voice database corresponding to a geographical area to which a pre-established geographical location belongs to obtain a wake-up instruction database corresponding to the geographical area, including:
and when the awakening voice data are determined to be in accordance with the language characteristics of the predetermined geographic area, adding the awakening voice data into the voice database corresponding to the geographic area to obtain an awakening instruction database corresponding to the geographic area.
In one possible embodiment, the method further comprises:
and deleting the awakening voice data from the awakening instruction database corresponding to the geographic area when the awakening voice data are determined not to conform to the language characteristic of the predetermined geographic area aiming at each awakening voice data in the awakening instruction database corresponding to the geographic area.

the language features not distinguished by Mandarin F, H may be determined to be language features of Fujian region;
the language feature of the mandarin chinese flat-warped tongue as opposed to mandarin chinese may be determined to be a language feature of the northeast region.
It is worth noting that while the voice databases corresponding to the same geographic area are continuously enriched, the voice databases corresponding to the same geographic area need to be continuously confirmed and analyzed to obtain the language features of the geographic area, and meanwhile, the language features of the wake-up voices of all users in the language databases corresponding to the geographic area are continuously compared.
If the awakening voice of the current user accords with the language characteristic of the current voice database, the language characteristic of the user is taken as the language characteristic sample of the geographic area and is integrated into the voice database corresponding to the geographic area; and if the awakening voice of the current user does not accord with the language characteristic of the current voice database, abandoning the awakening voice of the user and not integrating the awakening voice of the user into the voice database corresponding to the geographic area as the language characteristic sample of the geographic area.
Continuously confirming the language characteristics of the voice database corresponding to each geographic area, comparing the awakening languages of all users in the voice database with the confirmed language characteristics of the voice database, and integrating to obtain the awakening instruction database corresponding to each geographic area.
Based on the same public concept, the embodiment of the invention also provides a device for establishing the awakening instruction database.
